Description
技术领域
本发明涉及一种饮料的加工方法,尤其是涉及一种洛神花柠檬果茶的制作方法。
背景技术
洛神花为锦葵科木槿属一年生天然食品原料药用草本植物,又名:山茄子等,它具有食用和药用的双重性。洛神花其味酸、性寒,有益于调节和平衡血脂,增进钙质吸收,促进儿童发育,促进消化等。具有清热解暑、利尿降压、养颜消斑、解毒、解酒等功效。还有活血补血、养颜美容的功能。现代研究表明洛神花含有原儿茶酸、异黄酮素以及丰富的氨基酸、维生素等化学成分,能降低胆固醇和甘油三脂、抑制低密度脂蛋白的氧化、抑制血小板的凝集、降低血栓的形成、减少动脉粥状硬化,可有效地预防心血管疾病的发生。此外,洛神花还含有丰富的维生素C,有清凉降火、生津止渴的功效,可以用来冲泡茶和制作饮料。洛神花还有保肝、抗癌的功效。
柠檬,又称柠果、洋柠檬、益母果。因其味极酸,肝虚孕妇最喜食,故称益母果或益母子。柠檬中含有丰富的柠檬酸,被誉为“柠檬酸仓库”,果实汁多肉嫩,有浓郁的芳香气。因为味道特酸,故只能作为上等调味料,用来调制饮料菜肴、化妆品和药品。柠檬属于柑橘类的水果,含有丰富的维他命C,对促进新陈代谢、延缓衰老现象及增强身体之抵御能力都十分有帮助。柠檬含有烟酸和丰富的有机酸,其味极酸,有利于人体酸碱度的平衡。柠檬富有香气,能祛除肉类、水产的腥膻之气,并能使肉质更加细嫩,柠檬还能促进胃中蛋白分解酶的分泌,增加胃肠蠕动, 柠檬汁中含有大量柠檬酸盐,能够抑制钙盐结晶,从而阻止肾结石形成,甚至已成之结石也可被溶解掉,所以食用柠檬能防治肾结石,使部分慢性肾结石患者的结石减少、变小。 吃柠檬还可以防治心血管疾病,能缓解钙离子促使血液凝固的作用,可预防和治疗高血压和心肌梗死,柠檬酸有收缩、增固毛细血管,降低通透性,提高凝血功能及血小板数量的作用,可缩短凝血时间和出血时间,具有止血作用。鲜柠檬维生素含量极为丰富,是美容的天然佳品,能防止和消除皮肤色素沉着,具有美白作用。柠檬酸汁有很强的杀菌作用,对食品卫生很有好处,实验显示,酸度极强的柠檬汁在15分钟内可把海贝壳内所有的细菌杀死。
新鲜的洛神花容易氧化,不易贮藏,用于加工成洛神花柠檬果茶可实现对洛神花原料的综合利用,食用方便,且便于储存,提高其营养价值。
发明内容
本发明的目的是解决洛神花不易贮藏的问题,提供一种洛神花柠檬果茶的制作方法。
本发明解决其技术问题所采取的技术方案是:
一种洛神花柠檬果茶的制作方法,其特征在于:采用了三步制造工艺流程,一是洛神花汁的提取:选料→清洗→热烫→打浆→保温浸提→离心→酶处理→贮汁罐;二是柠檬汁的提取:选料→清洗→切片→蒸煮→打浆→酶处理→离心→胶磨→贮汁罐;三是混合调配与灌装:混合调配→均质→真空脱气→杀菌→灌装→成品,具体操作步骤为:
A、洛神花汁的提取:
①选料:挑选出新鲜、成熟、无病虫害的洛神花花苞;
②清洗:放入清水中浸泡,搅动5分钟,将花苞洗净;
③热烫:将洗净后的洛神花放入98-100℃的热水中进行漂烫15-18min,漂烫后,滤干备用;
④打浆:采用筛孔直径为0.3-0.5毫米的打浆机,添加一定量的水打成浆;
